what do u guys think

im looking at two diamond audio D312D4's with a ported inclosure do u guys think those would be some good subs i saw that they are in the highly recomended group heres what they are http://sonicelectronix.com/item_5527.html

if you power it well, and enclose it correctly, they'll sound terrific. The only warning i have is of the vendor, sonic, along with ike, are two vendors that i've always read shitty reviews such as late deliveries, mistakes, etc. Personally, i've ordered from both, sonic and ike, without a problem, maybe i just got lucky, or maybe those writing the reviews were unlucky... just thought i'd throw it out there.
